Thick wall seamless steel pipe

Thick-walled steel pipes are mainly used for petroleum geological drilling pipes, cracking pipes for petrochemicals, boiler pipes, pipes and high-precision pipes for automobile bearings, tractors, and aviation structures. The biggest difference between thick-walled and thin-walled steel pipes is the wall thickness. It is said that the thin-walled steel pipe is a drawing process, while the thick-walled steel pipe generally adopts the hot rolling process

Product Description

Seamless Steel Pipe

Carbon steel seamless steel pipe is a unique long steel product. The steel pipe has a hollow cross-section and is widely used as a pipeline for transporting fluids, such as pipelines for transporting oil, natural gas, gas, water and certain solid materials. Compared with solid steel such as round steel, the steel pipe has the same flexural and torsional strength and is lighter in weight. It is an economical section steel and is widely used in the manufacture of structural parts and mechanical parts, such as oil drill pipes, automobile drive shafts, Bicycle racks and steel scaffolding used in building construction, etc.
